Buying Guide: How to Choose the Best 5th Wheel Air Conditioner

Selecting the right air conditioner for your 5th wheel RV involves several key factors:

Cooling Capacity (BTU)

BTU rating determines how much space an AC unit can effectively cool. Large 5th wheels or motorhomes generally require units with 13,000-15,000 BTU, while smaller spaces might suffice with 5,000-10,000 BTU models. Consider your RV’s square footage when choosing.

Type of Unit

There are rooftop mounts and portable units. Rooftop units offer permanent installation with better cooling power but higher installation complexity. Portable units provide flexibility and easy removal but may have less cooling capability.

Energy Efficiency

Look for inverter technology or energy-saving certifications. Units consuming less power reduce strain on your RV’s electrical system and save battery life during boondocking.

Noise Levels

Noise can affect comfort, especially during sleep. Units labeled with noise levels in decibels allow comparison; quieter options typically range from 45 to 55 dB.

Compatibility and Fit

Check the dimensions and mounting requirements. Some rooftop ACs fit standard 14″ x 14″ openings, while others require specific fitting. Portable units need adequate ventilation space.

Durability and Weather Resistance

For rooftop models, weather-resistant construction with UV protection and insulation helps withstand outdoor elements and heat.

Additional Features

Features such as remote controls, multiple fan speeds, dehumidification, and adjustable vents enhance usability and comfort.

By balancing these considerations against your specific RV size, travel style, and power availability, you can select the best 5th wheel air conditioner to meet your cooling needs.
